Definition

Oxford Dictionary defines cloud computing as “The practice of using a network of remote servers hosted on the internet to store, manage, and process data, rather than a local server or a personal computer”.

In simple words,  Cloud computing is the way to access the files are over the internet (cloud) in the way ‘Pay Per Use’. The data is differentiated in types as servers, storage, databases, software, etc. Users can access the data based on their demands.

Companies offering cloud services are called cloud service providers.

Types (service models) of cloud computing services

Cloud computing services have the following types

  • IaaS
  • PaaS
  • SaaS

IaaS :

Infrastructure as a Service abbreviated as IaaS is the most basic type. In this type, other companies (third parties) holds the cloud computing elements like servers, networking, storage, software. They do also provide security, backup, and maintenance.

PaaS :

Platform as a Service (PaaS) is another cloud computing service in which there is the elimination of complexity of buying and managing the hardware layers.  This cloud computing service allows users to develop applications without the need to look into the code, hardware, and other things.

SaaS :

Abbreviated as SaaS, Software as a Service is a method of delivering the services over the cloud on-demand. We may also call this method ‘Application as a Service’. Usually, in this type of services, the user can access the data present on another person’s computer via a browser. There is no need to set up or install any application to access that data.

Deployment Models of Cloud Computing :

There are three ways of deploying cloud data. Let us see them in brief.

  • Public Cloud
  • Private Cloud
  • Hybrid Cloud

Public Cloud 

Public cloud is when the services are over the network open for public access. These services are mostly free. So, being in this model, users need not purchase any hardware or software infrastructure. Also, These are all managed by the cloud service provider. Amazon Web Services (AWS), Microsoft Azure are examples of the public cloud.

Private Cloud

This deployment model of cloud computing is generally used in single organizations. This can be managed by that organization itself or a third party. This type has more control of resources. Using this Private Cloud can improve business, but has the possibility of raising issues. So security should not be tolerated.

Hybrid Cloud

Hybrid cloud can be a composition of two clouds mentioned above. Such that, the data can be shared between the public and private type both. Consider an example where the company need not have a private cloud to process the temporary data. So for that purpose, the public cloud will be used. The private will also be used for more important data which not a temporary.

Benefits of Cloud Computing

  • Cost

The cost is much important for any business. Cloud computing certainly reduces the cost of buying the hardware and its management.

  • Adaptability

Cloud allows users to control the code. And allow adaptable applications.

  • Performance and Speed

The performance surely improves as the speed also increases if cloud computing is used.

  • Productivity

Productivity is another term which gets benefits from this computing.

  • Security

It does also offer a more secure environment.

Uses

  • To create a new Web Apps and Services
  • Host blogs and websites
  • Stream Audios and Videos
  • Mobile Services
  • Social Networking
  • Online Businesses
